Replacement Parts from Physical Samples
When an original replacement is difficult to obtain, a physical part can be the starting point for a manufacturing review. Send photographs and explain the failure before arranging a sample.
Discuss a Replacement PartWhen there is no original production drawing
In our documented case, a specialist rotor dynamic balancing provider supplied a damaged bearing retaining screw. A bearing failure had gone unnoticed and caused wear to the screw. It was not a routine wear item held in stock; the original replacement option had an estimated four-month ordering, production and delivery cycle.
From the sample to a manufacturing reference
Shenpu measured the damaged component and reconstructed a drawing. Worn features need interpretation: the measured condition is not automatically the original design dimension. Please explain how the part fits and operates, and provide any mating dimensions or existing specifications that can support the review.
One replacement, through the required processes
The team selected 42CrMo alloy steel for this project and produced one part through cutting, CNC turning, machining-center work, quenching and tempering, grinding and inspection. From receipt of the damaged sample, the part was ready for shipment in approximately 15 days. Transit time is not included, and this is not a standard lead-time promise.
Feasibility before a commitment
The replacement was installed and the customer's machine returned to service. This result supports a conversation about a similar problem, not a guarantee that every damaged or discontinued part can be reproduced. Suitability, available reference information and inspection requirements must be reviewed for each request. Submit only materials you are authorized to disclose; military and export-controlled projects are not accepted.
Send the information that defines your part
- Clear photographs of the whole part and damaged areas
- Its function, failure symptoms and known mating dimensions
- Required quantity, available documents and target dispatch date
PDF, STEP and photographs in JPG or PNG are accepted. Up to 10 files, 10 MiB total. For a physical sample, contact us before shipping.
